Hello OCN! I created this Laptop GPU cooler. What you do is put it on the side of the computer (Where the vent is) and it sucks the hot air into the heatsink, but it really works great.
- A video i made of it.
It uses a USB cable to get the power.
How i made it:
1. Cut a USB cable (i had to cut 3 to see which ones worked)
2. Get a heatsink (forgot what kind of connector) with a power cable
3. Shove the USB cables into the power cable (Some holes in it for a input)
4. Plug in the USB and away you go.
Conclusion
Well, it worked great, Temp came down from 60-70 C (On a 8800M GTS GPU)
to 50-55 C. Wow. Works WONDERFUL. Bigger fans wont work as well, as they require more power, so smaller = better.
Please note, i cannot guarantee it to work 100 percent perfectly, as in cooling performance, some fans work better than others. I tried this on another laptop, and it does not give the same results. For best use, put it under the fan (If there is a fan underneath the laptop) or putting it on the side.
ALSO, YOU MAY RUIN YOUR USB PORT PERMANENTLY IF YOU DO THIS INCORRECTLY.
I hope this was informative to OCN!
